Why I Choose Homemade Liquid Laundry Detergent

I had almost given up on homemade laundry detergent completely, when my good friend Keesha texted me and said she had a recipe and wanted to make it together! I had my doubts, but she told me her mom and her sister had both been using this kind forever and swore by it, so I decided I would give it a go. Holy cow.

How to Make Homemade Laundry Detergent

1.Start by grating your Fels-Naptha soap bar. Here is what the Fels-naptha soap looked like after grating it. You want to use the smallest grater that you have, so that it melts as quickly and easily as possible!

2. While you are grating your soap start four cups of water boiling.

3.Add your grated Fels-Naptha bar and stir over medium heat until soap is completely melted.

4. Next, fill your five gallon bucket up halfway with hot tap water.

Homemade Detergent Recipe Label & Storage

Be sure to clearly label your containers so that everyone knows they contain a detergent. Also, if you have young children be sure to keep your laundry detergent in a childproof container or on a high shelf. Here is the gallon jar I used, and here is a good five gallon bucket! I also love this gamma seal lid!

How much DIY Laundry Detergent does this recipe make?

This recipe makes a 5 gallon tub of liquid detergent. You only need ½ cup detergent for top loader machines and ¼ for front loader machines per load! It's easy to see how utilizing homemade laundry detergent can add up to a big savings!

It costs less than $10 to make 5 gallons of this laundry soap (not including the cost of the bucket). Which equals out to 160 ½ cup loads or 320 ¼ cup loads. Either way, there is a massive savings when comparing to store bought laundry detergents, even when they are purchased in bulk quantities.

Equipment

5 gallon bucket

Materials

4 cups boiling water
1 Fels-Naptha soap bar
1 cup washing soda
½ cup Borax
essential oils (optional)
5 gallon bucket

Instructions

Heat 4 cups of water until boiling.
Grate your Fels-Naptha soap bar (I just used a cheese grater) and add to boiling water. Stir continuously over medium low heat until soap dissolves and is melted.
Fill your 5 gallon bucket half full with HOT tap water, add melted soap, washing soda, and borax and stir well until all powder is dissolved.
Fill the bucket the rest of the way to the top with hot water, stir, cover, and let sit overnight to thicken.
The next day, stir well and fill an old laundry detergent container with detergent.If desired, add your essential oils at this point! I use Doterra citrus bliss.

Notes

Shake well before each use, because detergent can separate a bit.
Top load machines use ½ cup per load, front load machines use ¼ cup per load.
Here is the gallon jar I used, and here is a good five gallon bucket!
